Abstract

Imino(triphenyl)phosphorane, Ph3P[double bond, length as m-dash]NH (1), reacts with nitrile complexes of Pt(IV) to generate hydrolytically sensitive [PtCl4{NH[double bond, length as m-dash]C(R)N[double bond, length as m-dash]PPh3}2] (R = Me 2a, Et 2b, Ph 2c), and with the Pt(II) complex [PtCl2(EtCN)2] to give [PtCl2(EtCN){NH[double bond, length as m-dash]C(Et)N[double bond, length as m-dash]PPh3}] (3) and [PtCl2{NH[double bond, length as m-dash]C(Et)N[double bond, length as m-dash]PPh3}2] (4); X-ray crystallography performed upon (2b) and (3) confirms the presence of an imine/nitrile addition ligand bound by the terminal nitrogen.
